Filed: 1983-06-29
Abstract: PURPOSE:To easily apply the initial pre-pressure between rollers necessary for the rotation drive and facilitate the assembly by forming at least one or more rollers among three rollers forming a planet type friction speed changer with a profile memory alloy. CONSTITUTION:When an input shaft 6 is driven, a solar roller 1 formed in one body with it is rotated, and planet rollers 2-4 in contact with the solar roller 1 by pressure are further rotated with axes 7-9 serving as a center respectively. Thereby, a ring roller 5 is rotated and the said axes 7-9 are rotated around an output shaft 11, thus the power is transmitted to the output shaft 11. In this case, the planet rollers 2-4 are formed with a frofile memory alloy and are incorporated into a speed changer with their volume made small, and the overall speed changer is assembled with a gap left between the solar roller 1 and ring roller 5. Then, the planet rollers 2-4 are expanded in volume due to the environmental temperature during the load operation of the speed changer, and a proper contact pressure is generated between the solar roller 1 and ring roller 5.
